radius = half the diameter ------> 16/2 = 8
pi = 3.14
64*3.14 = 201
If you reduce the fraction to a mixed number than it would be 2 2/5 but if you want to reduce it to a decimal it would be 2.4
Unnecessary comment, this does not fit towards Mathematics.
Number of unmarked wolves: 928 - 232 = 696
probability of next wolf being unmarked = 696 / 928 = 0.75
0.75 x 100 = 75%
